The Alsatian Colorado

Why is it called the Alsatian Colorado... when it's just across the border in Germany? Our German neighbours call it the Altschlossfelsen or "Old Castle Cliffs". In any case, this easy horse ride between France and Germany, with no major difficulties or steep slopes, allows you to discover this beautiful pink sandstone rock formation, hidden among the vegetation.
A short, easy hike, ideal for families with children who enjoy walking.

Description of the walk

On leaving the village of Roppeviller, heading east, park on the left in the large car park (D86a)

(S/E) Turn right as you leave the car park towards the village.

(1) Then take thefirst street on the right, which continues as a fairly steep path.

(2) When you reach a forest path, take it on the right and follow it for about 1.5 km. The path then makes a sharp turn to the right.

(3) At this point, pay close attention: a fairly inconspicuous path branches off to the left and climbs up to Rocher de Diane.

(4) At Rocher de Diane (sign on the left), you can admire a Roman fresco depicting Diana the Huntress with her bow and quiver, accompanied by two dogs and two other gods.
Then descend by following the path that runs along the border (use the border markers as your guide) until you reach the junction with the path marked with a yellow cross.

(5) Take the path opposite (the path marked with a yellow cross branches off to the right) and continue along the French-German border until you reach the start of the Altschossfelsen rock formation ("old castle cliffs").

(6) Turn left at the sign for Altschlossfelsen and begin your exploration of this remarkable site by walking along the top of the rock formation.
If in doubt, follow the signs for "Rundweg".
There are a few open areas that are ideal for breaks or picnics. There is also a beautiful viewpoint over the wooded area of the Bitche military camp, with a few tables and benches. Towards the end, the path descends to the left at the foot of the rocks. Continue in the same direction until you reach the end of the rocky outcrop.

(7) At the turning point of this hike, there is a passage between two rocks that allows you to easily cross to the other side of the rocky outcrop. Return via the wide path that passes under the cliffs and enjoy the play of colours and light in the pink rock, caves and crevices. Continue along the path, passing under the large arch, then return to the intersection you passed on the way out, at the start of the rocky outcrop.

(6) Take the border path on the right (the one you took on the way there) to the previous WP.

(5) This time, take the path on the left marked with a yellow cross and follow it straight ahead along the meadows to the car park (S/E).

Notes

There are no water sources along this route. Remember to bring enough to drink, especially when it's hot!

Hiking boots or good sports shoes are sufficient.

The 2½-hour hike is only a rough estimate... Personally, we took the time to admire the rocks, take photos... and it took us longer!

A very interesting and scenic route, but there isn’t enough signposting on the way up the southern Colorado trail (some of the Red Discs are missing)

A walk worth doing; you might also want to use the other route descriptions, including this one, depending on how much time you have.

A lovely walk to discover a natural wonder.

A stunning route, winding through rocky outcrops and woodland. Best enjoyed in sunny weather but outside the peak season (early in the morning?)
Large car park at the edge of the village

I’ve wanted to go on this hike for years and, to be honest, I’m absolutely delighted.
Thanks, Visorando

Easy route, mostly through forest, with a slight difficulty of a few metres of stony path.
Easy access and large car park at the starting point.

Colorado Alsacien is located in Lorraine, more specifically on the border between Moselle and Germany.
The car park is located at the start of the route at the Roppeviller exit.

Superb hike, a real change of scenery.
Easy.
There were quite a few people at the car park, and we were worried there would be too many, but no, it's so big that we quickly found ourselves at a respectable distance from each other.
A must-do

A very beautiful walk. It should be noted that the signs and markings are much more frequent (and therefore reassuring) on the German side.

Superb rock formation. Best visited during the week and out of season, as the size of the car park says a lot about how busy the site is! I don't understand why it's called "Alsatian Colorado" (although the name is widely used). The rocks are in Germany, and the village of Roppeviller is in Lorraine... Be careful if you prefer to go over the rocks at point 6 first, as it's not easy to find. The lower path is much more obvious.

The start of the circuit should be changed to the car park at the edge of the village, which is also where it finishes
so that people don't park in the small car park near the church, where parking is prohibited (except for the church and restaurant)
Otherwise, it's a very beautiful hike with magnificent scenery

The walk can start not at the church but at the end of the road just after the village, which has a very large car park.
however, the walk through the forest from the church is quite pleasant.
The site is exotic and incredible due to the unique features of its geological formation.
The route is not difficult if you follow the main trail, but be careful, as you sometimes have to lift your knees more than 40 cm off the ground, and I can confirm that there are intertwined roots.
A shaded trail with exceptional rock formations!
It's a good idea to bring a packed lunch to eat on site, making sure to take all your rubbish away with you, of course!

Superb hike, advertised as easy, but in our opinion some sections are difficult for older walkers.

A very beautiful, shaded hike. We lost our way at the fork leading to Diane's Rock and returned via point 5 on the way out. Never mind
